as de manual says :(note: used google translate)

Transponder number (T)Command Description: Used to read a single transponder. If there areno transponder in the field, gives the reader 'NOTAG'as an answer. The transponder number is then 10positions (eg AC3F00D1B4) as hexadecimal codedASCII character sequence indicated.Format: CT Example: FFCT23 FFCT03C2208CFF64 reads the current transponder number 03C2208CFF.
